Attention Filers: The Premerger Notification Office has experienced a few changes since we’ve come to our new home in the Constitution Center. Some of those changes can affect the arrival of your filings by messenger. Due to the security procedures and physical size of the Constitution Center, once a messenger has arrived at the building it takes in excess of 10 minutes to reach the PNO office. While the PNO is open to accept HSR filings at its 5th floor intake window from 8:30 AM until 5:00PM, Monday through Friday, a messenger arriving after 4:50PM cannot make it from the loading dock entry, through security, to the 5th floor HSR window by 5:00PM, so building security is turning away newly arrived messengers at 4:50PM each day. If you want to guarantee that your filing arrives at the PNO window by 5:00PM, please send any messenger with ample time to arrive at the building well in advance of 4:50PM.

We’re sorry for any inconvenience this might cause. Thank you.

REMINDER: Sometimes filing parties reference an attachment in response to Items 4 through 8 of the HSR Form instead of providing the requested information in the Form itself - for instance, a separate log of 4(c) documents. If you do this, PLEASE place the attachment behind the page of the Form to which it relates or at the end of the Form itself. This information is a necessary part of the Form and needs to be provided in all originals and copies of the Form filed with the FTC and DOJ. DO NOT intersperse such referenced attachments for Items 4 through 8 among the documentary attachments (e.g., placing the separate 4(c) log at the beginning of the 4(c) documents), as those documents are not part of the Form itself.

The MMA Filing Instructions (for brand name drug manufacturers and generic drug applicants who file certain agreements with the Antitrust Agencies under the Medicare Prescription Drug and Improvement Act) have been updated with the new address for the FTC's Premerger Office. (July 2014)

Attention: The Constitution Center does not allow messengers with cleats into the building. Please DO NOT send messengers with cleats to deliver HSR filings. Starting immediately, the PNO will not meet messengers with cleats at the loading docks. (June 2, 2014)

Important Announcement: Building management at the Constitution Center has changed the security procedures for the delivery of HSR filings. Messengers delivering HSR filings must now enter the building through the loading dock entrance on 6th Street SW near School St. SW. Complete directions can be found here. Note that messengers will not be allowed to wear cleats into the building.

The Premerger Office is moving! As part of the consolidation of FTC staff, the Premerger Notification Office will be moving to new offices on the 5th floor of the Constitution Center on April 28. For more details, see our new blog post here. We will be providing additional information, including new security procedures for filing delivery, on this page and on the blog in the coming weeks.

Effective immediately, all filing fee questions should be directed to Theresa Kingsberry at tkingsberry@ftc.gov or at 202-326-3100. (January 2014)

Effective Jan. 2, 2014, brand name drug manufacturers and generic drug applicants who file certain agreements with the Antitrust Agencies under the Medicare Prescription Drug and Improvement Act should complete the MMA Cover Sheet and attach it to the agreement prior to filing.
